Infrared devices detect a different wavelength than a normal camera or the naked eye, viewing the world through heat rather than light. The image from an infrared camera can show warm objects in a lighter color where cold objects will appear darker. So, how can infrared devices be beneficial for commercial roofing? Here are some thoughts to consider.
Using Infrared for Roof Surveys
Infrared cameras have been used in roofing since the 1970s as an inexpensive and nondestructive way to detect moisture within the underlying insulation. Wet areas reflect and retain heat differently than dry parts of a roof. By using an infrared camera, roofers can “see” where wet patches are, without penetrating the roof system.
4 Types of Infrared Roof Surveys
There are four different ways to use infrared cameras to detect roof moisture:
- Rooftop moisture survey: Usually roofers will conduct an infrared moisture survey by walking on top of the roof. Aside from obvious tears and sealing problems, a qualified roofer will know how to examine for hidden sources of moisture.
- Under-roof moisture survey: Sometimes, roofers will want to use infrared to examine a roof from the inside. This method can help find moisture that has penetrated the roof surface and is trapped inside the building envelope. Certain metal roofs won’t retain moisture on the surface and will require an under-roof moisture survey.
- Elevated roof moisture survey: By moving above the roof to capture infrared images, roofers can get a look at a larger portion of the roof’s surface. This gives a better picture of the scope of the water damage and can also help find wet areas that would be hard to see close up.
- Aerial roof moisture survey: This is the most accurate and efficient type of roof survey. Using an aircraft or a drone, roofers can get an image the entire roof to detect slight differences in temperatures that indicate moisture build up.
Generally, Infrared surveys are followed by test cores to confirm actual moisture infiltration and gather further details of the effects. With the large investment in roof insulation on modern roofs, non-destructive moisture detection surveys, like Infrared, are more important than ever.

Companies decide to go green for many reasons. It may be due to a core business value or for a chance to connect with customers. It may just be for the cold hard cash savings that come from energy efficiency. Whatever the reason for becoming more eco-friendly, facility managers shouldn’t overlook the importance of choosing the right type of roof to maximize energy savings and eliminate waste. Here are five environmentally-friendly options for commercial roofs:
- Solar Panels—The large empty space on a commercial roof is the perfect place to put solar panels to offset a building’s electricity use. New roofs can be specially outfitted to support the weight of solar panels. Older roofs will likely need some modification to safely secure panels on the roof. Though a solar company may say they can install the panels, it’s important to always use a professional roofer to ensure that the installation doesn’t do any damage.
- Green Roof—Not only do roof plants help fight climate change, but they also can help moderate the temperature of a commercial building and improve air quality in the surrounding area. Green roofs are ideal for urban areas where there is little other surrounding vegetation.
- White Roof—Roofs with white or light-colored membranes are considered “cool roofs” because of their ability to reflect more of the sun’s rays away from the building. In hot places, cool roof systems can help reduce the need for air conditioning in the summer, lowering the building’s electricity bill.
- Metal Roof—Metal is one of the most eco-friendly materials for roofs. A metal roof made from recycled materials can last up to 60 years, and the material can be re-used again once it is time to replace it. Metal is also reflective, keeping buildings cool in the summertime.
- Recycled or Biodegradable Roof Material—There are plenty of ways to use recycled or biodegradable materials for a more traditional commercial roof style. Reclaimed clay can be used in tile roofing. Sustainably harvest wood shake is biodegradable and can be used for shingles. Old tires can also be made into rubber roofing material that can last for many years.
